Modeling and Simulation of Renewable Generation System: Tunisia Grid Connected PV System Case Study

Abstract

This paper seeks to evaluate and study Tunisia Grid-Connected system (PV/Wind Turbine), to improve the electricity production without interruption using renewable energy during daily as well as seasonally periods. In this vein, in order to manage and control the dynamic power stability, two modes have been treated, whether with or without integration of photovoltaics. To distinguish the variations between the two modes, the integrations of Renewable energy will be between 15% and 30%. To perform the correct system operations and to meet load requirements during the peak periods. Considering the impact of included modes and the Renewable energy source integrated into the grid, an accurate fault current characteristic analyzes have been treated. A novel protection scheme using PSSE simulation environment obtains the results and observations is then proposed. The obtained results proven that the loss of the generators have an undesirable effect on stability.
